Cabinet LED lighting makes everyday life easier and completes your home's appearance. When light is positioned correctly, cabinet contents are easier to find, display case items are better showcased, and the kitchen's overall design feels more considered. LED strips work well in cabinets, display cases, open shelving and kitchen units when you choose the right light output, colour temperature, profile and power supply.
Good cabinet or display case LED lighting isn't just decorative. It can function as practical task lighting, ambient lighting or as part of the kitchen's general illumination. In this guide, we'll cover how to choose the right LED strip for cabinets, when to use LED profiles, how colour temperature affects the result and which mistakes to avoid.
If you're also planning other kitchen lighting, read Valotehdas's guide to LED lighting for kitchens. For more information on COB LED strips, see the COB LED article and for light tones, the guide to colour temperatures and Kelvin.
Why Choose LED Lighting for Cabinets and Display Cases?
Cabinet and display case LED lighting improves spatial usability and creates a polished impression in your interior. In the kitchen, light helps locate items in deep cabinets, highlights open shelving and makes the worktop area more pleasant. In the living room or dining area, display case LED lighting showcases glassware, crockery, books or ornaments without heavy lighting fixtures.
LED strips are practical for these applications because they take up little space and can be installed discreetly within profiles. Light can be positioned at the cabinet's front edge, rear edge, side or beneath shelves depending on whether you want functional or ambient lighting.
Common applications for cabinet LED lighting include:
- under-cabinet lighting for kitchen units
- internal cabinet lighting
- lighting for display cases and glass-fronted cabinets
- lighting for open and decorative shelving
- additional lighting for utility rooms and wardrobes
- ambient lighting in kitchen and living room areas
Choosing LED Strips and Profiles for Cabinets
LED strips installed in cabinets should be chosen according to their intended use. If the light's purpose is to help see cabinet contents or illuminate worktops, you'll need more light output than for purely ambient display case lighting. However, if the LED strip is installed in a glass display case or inside open shelving, the light should be soft and non-glaring.
| Application | Suitable Solution | Considerations |
|---|---|---|
| Under kitchen cabinet | LED strip in profile with opal cover | Light should reach worktop without glare |
| Display case | Low or medium output LED strip | Choose soft light and neat wiring |
| Internal cabinet lighting | LED strip on side or under shelf | Position light to avoid glare when opening |
| Open shelving | COB LED strip or dense LED strip | Even light line completes visible installation |
LED profiles are an important part of neat installation. Profiles protect LED strips, help keep the strip straight and allow the use of opal covers. Opal covers soften light and reduce visible LED dots, which is particularly important in visible cabinet and display case solutions.
COB LED strips are an excellent choice when you want the most uniform light line possible. They're particularly suited to visible shelving, display cases and under kitchen cabinets where a dotless or nearly dotless appearance is part of the finished result.
Colour Temperature and Lighting Atmosphere
Colour temperature affects how cabinet or display case LED lighting appears in practice. Warm light creates a softer, cosier space, whilst more neutral light gives a clearer, fresher impression.
| Colour Temperature | Effect | Suitable Application |
|---|---|---|
| 2700K | Warm and soft | Display cases, ambient lighting, kitchens adjoining living rooms |
| 3000K | Warm but clear | Kitchen cabinets, open shelving and general use |
| 4000K | Neutral white | Worktops, utility rooms and clearer task lighting |
If cabinet lighting relates to kitchen worktop illumination, 3000K or 4000K is often a practical choice. If the lighting's purpose is to enhance a display case or create atmosphere, 2700K or 3000K may be more suitable. You can read more about choosing colour temperature in Valotehdas's Kelvin guide.
Installation Tips and Practical Considerations
Successful cabinet LED lighting depends largely on positioning. The same LED strip can look very different depending on whether it's installed at the cabinet's front edge, rear edge, side or beneath a shelf.
Under kitchen cabinets, LED strips are often best positioned so light reaches the worktop rather than directly into users' eyes. In display cases, light can be positioned at the side or top edge to highlight items softly. For internal cabinet lighting, consider door opening, shelf shadows and concealing wiring.
Checklist Before Installation
- Measure the cabinet, display case or shelf to be lit accurately.
- Decide whether light is for functional or ambient use.
- Choose LED strip colour temperature and output.
- Select appropriate LED profile and opal cover.
- Plan power supply and wiring location.
- Test LED strip before final fixing.
- Ensure fixed electrical installations are completed by a professional.
If LED strips are being installed in multiple cabinets or over long distances, power supply sizing and voltage drop should be considered beforehand. In short cabinet installations this is usually straightforward, but in longer installations, planning helps achieve a neat result.

Common Mistakes in LED Lighting
The most common mistake in cabinet LED lighting is positioning light too visibly. If the LED strip is directly visible to the eye, the result can be glaring and look unfinished. Profiles and opal covers help with this, but choosing the installation location is also important.
Another mistake is selecting too cool or too warm a colour temperature. Colour temperature should be matched to the space's other lighting, furniture colours and intended use. A third mistake is undersizing the power supply or planning wiring only at installation stage.
- LED strip installed without profile in a visible location.
- Light positioned to glare at the user.
- Colour temperature doesn't match other kitchen lighting.
- Power supply incorrectly sized.
- Cables and connections left visible.
- Dimming not considered before installation.
Frequently Asked Questions About LED Cabinet Lighting
Which LED strip suits internal cabinet lighting?
Low or medium output LED strips installed in profiles generally suit internal cabinet lighting. If the light remains visible, COB LED strips or dense LED strips with opal covers provide a neater light line.
How do I choose the right colour temperature for cabinets?
2700K suits ambient lighting, 3000K general use and 4000K clearer task lighting. The choice should be made according to cabinet materials and the space's other lighting.
Can LED lighting be dimmed?
Yes, if the LED strip, power supply and dimmer are compatible. Dimming should be planned before installation so all components work together.
Which profiles are recommended for cabinet LED strips?
Cabinets typically use low surface-mounted profiles, recessed profiles or corner profiles. Opal covers are a good choice when you want softer light and fewer visible LED dots.
How can I ensure neat and durable installation?
Choose an appropriate profile for the LED strip, plan wiring beforehand and test the light before final fixing. Fixed electrical installations should be left to professionals.
Does the same LED strip suit both display cases and under kitchen cabinets?
Sometimes yes, but the intended use determines this. Worktops usually need more light, whilst in display cases soft, non-glaring lighting is more important.
